-40 = -48 × impossible

___________________

5. solution :

-3+4x+12x+24 = 28x +12-3

-3+24-12+3=28x-12x-4x

27-15=12 = 2x - 16x =12x

12 = 12x

x =1

6. solution :

24-3x+9-6 = -8x+20+5x+7

8x-5x-3x = -24-9+6+20+7

0=0

x can be every number you think because they are always equal to each other .

examination :

if you consider x as 1 :

24-3+9-6=-8+20+5+7

24=24

or if you consider x as 2 :

24-6+9-6 = -16+20+10+7

21 = 21

__________________

7 . solution :

3(x-2) = 3x+4

3x-6 = 3x+4

3x-3x = 10

0 = 10

if you consider x as 1 :

3-6 = 3+4

-3 = 7 × impossible .
